While flying the A350 during a flight I encountered an issue with the Static Discharge Wick, when at low setting there seems to some magenta flashes on the wingtip and on the Static Discharge Wicks. It seems to be quite persistent as it can be seen from multiple camera angles and also during the day. I’ve attached a video showing what I see.
Just tested it and I can only reproduce if I have one of the three graphic settings set to low or if they are all set to low. It could be high, high, low and it appears but if neither are low then it doesn’t appear.
